54 Fillers Fillers Filling and fairing will streamline the surface of your boat, improving hull performance through the water, and giving clean, smooth lines on the topsides. If the substrate is damaged, you’ll need structural filling and fairing. Unifiller A single component conventional filler. Use for spot filling minor blemishes and screwheads above the waterline. When filling larger areas, you may need to apply several layers as Unifiller shrinks on curing. 5 o C/40 o F Minimum application temperature Temp Touch dry Dry to sand Tool clean Film thickness Tools 10ºC 4.5 hrs 7 hrs Thinner No 3 0.5mm per coat 20ºC 2 hrs 3 hrs Epoxy Filler A two component, solvent free, epoxy filler. Use for a variety of filling and fairing jobs both above and below the waterline. Can be applied in thick coats up to approximately 5mm without runs or sags. Fair before overcoating with relevant primer. 5 o C/40 o F Minimum Pot life at 20 o C Mix ratio application temperature Mixed product: 1hr 1:1 Temp Touch dry Re-coat (min/max) Tool clean Film thickness Tools 10ºC 16 hrs 16 - 48 hrs Degreaser 5mm per coat 20ºC 8 hrs 8 – 24 hrs 99611 350g 130ml 1l
Antifoulings and bottom coats Fouling not only makes a boat look unsightly, it can also foul propellers and outdrives, block engine water inlets and outlets, slow down the boat speed, increase fuel costs and ultimately damage the hull substrate/surface. <strong>Paint</strong>ing a boat’s underwater area: • protects its substrate/surface • avoids undue hull roughness. (Roughness increases resistance through the water, causing lower speeds and consuming more fuel.) Fouling varies widely depending on temperature, salinity and water quality. Differences in levels and types can be dramatic, even on boats moored in what seems to be the same environment, as fouling conditions are affected by sunlight/ shade, temperature and flow of water, pollution levels and water inflows. Fouling grows faster in sunlight, so is first seen on the waterline and rudder. Water surface dirt and pollution can adversely affect the antifouling. Key advice: Put extra layers on the rudder and waterline where more aggressive water flow takes place. How antifouling works Antifouling paints release bioactive ingredients. The bioactive materials used today are mainly cuprous oxide and booster organic biocides. They’re water-soluble and, when released, lethal to fouling organisms. Different types of antifouling paint release biocides/toxicants in different ways. There are three main types: • Self Polishing/Erodible • Hard • Traditional/Soft. These are explained on the next page. Choosing the right product You should consider: • boat type • sailing pattern & speed • geographic location and characteristics of the mooring • any existing coating • environmental and legislative issues in the area where you apply the product and sail. 55 Antifoulings and bottom coats
